FIG. 9 is a perspective, partially schematic view of a wearable spraycanister with trigger and safety mechanism in accordance with one ormore preferred embodiments of the present invention, and FIG. 10 is anexploded view of the wearable spray canister with trigger and safetymechanism of FIG. 9.

Positioned on the exterior, a top vessel 110, is the valve housing 112,which together form a single interior cavity. Inserted into the valvemechanism contained in the valve housing 112 is an actuator 116 thatwhen pressed allows the release of the contents trough the spray insert118. This is shown in some detail in FIGS. 9 and 10.

In FIG. 9 a cover 114 is shown connected to the vessel 110 via a coverconnection groove 120. Positioned on the plane surface is the sprayopening 124. The spray opening 124 is located at the spot on the cover114 directly a top the position of the spray insert 118 when theactuator 116 is triggered. Adjacent to the cover connection groove 120is a housing connection groove 122, which may be a means to add aperipheral like a clip, wrist band, necklace, adhesive or other housingfor functional and/or aesthetic purposes. Also, shown on cover 114 is asafety tab opening 126 and a trigger tab opening 128 which, when cover114 is seated, allows a trigger tab 130 and a safety tab 132 topartially protrude beyond the circumference defined by the vessel 110.This embodiment describes an indentation around the exterior of vessel110, but other attachment methods are possible.

Attached to actuator 116 is the trigger tab 130 which slides parallel tothe top plane of the vessel 110 toward the valve housing 112. Similarlythe safety tab 132, also moves along the top plane of vessel 110 towardsthe opposite side of the valve housing. Positioned on the safety tab 132are indentations identified as obstruction relief 138. Positionedadjacent and independent moving is a safety obstruction 136. Spring 134are secured in the longitudinal centers providing resistance at one endagainst the trigger tab 130 and at the other end the safety tab 132.FIG. 11 shows the assembly in its stand-by mode at the ready with thesprings 134 relaxed.

FIG. 12 illustrates the assembly in its active mode with the springs 134compressed and the safety obstruction 136 seated in the obstructionrelief 138 allowing the actuator 116 to be pressed towards the valvehousing 112.

To activate this invention for personal protection, the user squeezesthe trigger tab 130 and safety tab 132 towards each other. The spring134 keeps the tabs in stand-by mode until activated by the user.

To prevent accidental activation, the trigger tab 130 is blocked frommovement by the safety obstruction 136. Movement is preferably onlypermitted when the trigger tab 130 and the safety tab 132 are pressedsimultaneously. When this happens the safety tab 132 moves theobstruction relief 138 cutout directly adjacent to the safetyobstruction 136. The movement of the trigger tab 130 towards the valvehousing 112 forces the actuator 116 to pushes away the safetyobstruction 136 into the obstruction relief 138 allowing the actuator116 to open the value in the valve housing 112, releasing the contents,which is under pressure, from the interior of the vessel 110 through thespray insert 118. Based on the content's properties, the spray insert118 is designed to maximize the shape and characteristics of the spray.

Contents may include, but are not limited to, one or more chemicalirritants such as pepper spray, mace, tear gas, chloroacetophenone, CNB,CR, red gel, and criminal identifying gel.
